Let's answer the a part of the question to find the z reflected.
00:40
Mu is equal to m v perpendicular square by 2b is equal to a constant.
00:49
Let this be equation number 1.
00:52
And v perpendicular square is equal to 2 by 3 v square and let this be equation number 2.
00:59
Then v perpendicular reflected square is equal to v square by v parallel which is equal to 0 at reflection point.
01:13
At reflection point and let this be equation number 3.
01:19
From 1, 2 and 3, from equation 1, equation 2 and equation 3, mv perpendicular square divided by 2b0 is equal to mv reflected square divided by 2b reflected.
01:42
Which implies b reflected is equal to 3 by 2 b0.
01:49
Let this be equation number 4.
01:52
From b2.
01:57
From bz is equal to...
